The equation y = 7x gives the relationship between the number of road projects, x, and the number
of weeks it takes a crew of workers to complete all the projects, y. What is the constant of proportionality? What does it mean in this context?
The constant of proportionality in this equation is 7.
In this context, the constant of proportionality represents the rate at which the crew of workers completes road projects. It indicates that for every increase of 1 in the number of road projects, it will take the crew 7 weeks to complete all the projects.
